installed, all such devices must be open and clean during unit
operation.
2.4 MAKE-UP WATER SUPPLY CONNECTION
A. The automatic water make-up system continually monitors the
reservoirtankandllsitwhenneeded.Connectasfollows:
1. Usingappropriatelyratedhoseoruid
piping connect the “water make-up”
connectiontotheplant’swater
source.
2. Minimum make-up water supply pressure is normally 20 psi.
3. Install an owner supplied shut off valve in the make-up
water supply line. Install this valve on the outside of the unit.
4. Useabackowpreventiondeviceasmayberequiredby
local codes to prevent possible contamination of potable
water.
B. Do not use automatic water make-up system when operating
with glycol below 48°F.
2.5 AIR COOLED CONDENSER
A. Air-cooled condensers require ambient air temperatures between
60°Fand95°Fforefcientoperation.Operatingabove95°Fmay
result in elevated condensing pressures and eventual shut-down
on the high pressure limit switch. Air temperatures below 60°F
may result in over condensing pressures and cause a low pressure
refrigerantfault.ConsultwiththeManufacturer’s service department
for more information on operating with ambients air temperatures
above 95°F or below 60°F.
B. Airowisgeneratedbythemotor
mountedfans(gure2.4A)or
centrifugalblowers(gure2.4B).
Airowisfromtheoutsideofthe
chiller, through the condenser and
exhausted through the top of the
unit. On centrifugal blowers models,
exhaust air can be ducted outside
oftheplant’sinteriorenvironment.
Special duct work is required and
